Energy Loss?
Hey plz write formulas u use and if u have time step by step... but dont understand this- i know ur menna work out kinetic energy and then energy meant to travel or something but....
A ball of mass 0.2kg drops from height of 10.0m and rebounds to a height of 7.0m Calculare the energy lost on impact with the floor. Neglect air resistance

The potential energy initial is: Uin=m g h1 = 0.2*9.8*10 = 19.6 J
the potential energy final is: Ufi = mgh2 = 0.2*9.8*7 = 13.72 J.
The kinetic energy is 0, then the energy loss is:
Uin - Ufi = 19.6 -13.72 = 5.88 J.
